Congenital absence of the gallbladder is an extremely rare embryological aberration that is frequently mistaken for cholecystolithiasis; the aim of this study is to investigate the diagnostic methods for agenesis of the gallbladder. Two surgically confirmed gallbladder agenesis cases in our hospital and 75 cases of gallbladder agenesis reported in the literature in China were reviewed. It is ex...

Dental agenesis is one of the most common congenital craniofacial abnormalities. Dental agenesis can be classified, relative to the number of missing teeth (excluding third molars), as hypodontia (1 to 5 missing teeth), oligodontia (6 or more missing teeth), or anodontia (lack of all teeth). Tooth agenesis may occur either in association with genetic syndromes, based on the presence of other in...

Tooth agenesis is the most common of all dental developmental disorders. The mandibular second premolars are the teeth most commonly found missing (2.2 to 4.1%) after the third molars. There are more studies on tooth agenesis than the other malformations but yet they are limited. This article reviews the studies related to agenesis of mandibular second premolars and the underlying mechanisms be...

The combination of pulmonary agenesis and anophtalmia or microphthalmia has been described previously. This condition is known as Matthew-Wood syndrome and PDAC syndrome (pulmonary hypoplasia/ agenesis, diaphragmatic hernia/eventration, anophthalmia/microphthalmia, and cardiac defect). We report a sporadic case of female infant with the combination of bilateral microphthalmia, unilateral right ...

Shape variation in trophicmorphologybetween species in two trophic guilds (zooplankton and epilithic algal feeders) was investigated using landmark-based geometric morphometrics. Three disarticulated bone elements from the head region were examined; the neurocranium, the premaxilla and lower jaw. From separate analyses of each bone element, signiŽ cant shape variationwas identiŽ ed between spec...

Congenital absence of maxillary permanent canines is an extremely rare condition, which may appear as part of a syndrome or as a nonsyndromic form. Nonsyndromic canine agenesis combined with other types of tooth agenesis has occasionally been described in the literature but isolated cases are rarely observed. This report presents an isolated case of maxillary permanent canine agenesis in a heal...

Congenital unilateral renal agenesis occurs in 0.93–1.8 per 1000 autopsies, and is usually diagnosed on an incidental imaging examination. Genital anomalies occur in 37–60% of females and 12% of males with congenital unilateral renal agenesis. Abnormalities in females include agenesis, duplication, rudimentary, unicornuate or bicornuate uterus, double or absent vagina, absent or hypoplastic ova...
